(2020-04)In this study, the purchasing patterns of fresh produce amongst Dalhousie students on the Halifax campuses are identified and assessed in order to determine correlating factors and variables pertaining to the logistics ... -
The Chemical Composition of Granite-Related and Mineralization-Related Tourmaline in Nova Scotia
(1987-04-15)Tourmaline is a common accessory mineral which occurs in a wide variety of mineralogical settings. This mineral is commonly found in sedimentary, metamorphic, and granitoid intrusive rocks and their associated aplites, ... -
Identification of the Carrier of Magnetization in a Basalt Core from Bermuda
(1987-04-15)Peckenham (1981) attempted to use the magnetic properties of a basalt core from Bermuda to help him define the stratigraphy of basalt flows present in the core. The results of his investigation were not helpful. Magnetic ... -
The Petrology and Geochemistry of the Port Mouton Migmatites
(1987-04-15)This study is centered on the migmatites found along certain portions of the contact between the Port Mouton pluton of Shelburne and Queens counties, Nova Scotia, and the local host lithology. The field relations, petrology ... -
Regional Mapping and Petrographic Study of a Silurian Gneissic Complex, Belle Cote Road, Cape Breton, Nova Scotia
(1987-04-15)The Leblanc Lake area is located in the central Cape Breton Highlands south of the Cheticamp River. The main study area is situated along Belle Cote Road, one of the numerous logging roads in the region. Mapping at ... -
Paleosols of the Westphalian D Sydney Mines Formation, Sydney Basin, Cape Breton, Nova Scotia, Canada
(1992-04-15)Lacustrine-deltaic deposits in the Sydney Mines Formation contain paleosols. Three soil profiles (1 m, 1.2 m, and 0.9 m long) sampled over an 11.8 m interval of drill core taken ca. 200 m offshore Point Aconi, Cape Breton, ... -
A Subsidence, Compaction, Pressure, Temperature, and Maturity History of the Hibernia B-08 Well, Grand Banks, Newfoundland
(1992-04-15)The Jeanne d'Arc basin is one of several of Late Triassic basins in Atlantic Canada, some of which contain significant quantities of hydrocarbons. The Jeanne d'Arc basin has extensive overpressuring associated with the ... -
Genesis of the Volcan Copiapo Sulphur Deposits, Maricunga District, Chile
(1991-04-15)The Miocene age Copiapo Volcanic Complex is located in the heart of the Maricunga gold mining district in the southernmost part (Latitude 27oS) of the Andean Central Volcanic Zone. The largest cone in this complex, Volcan ... -
Seismic Stratigraphy of the Exmouth Plateau
(1991-04-15)The Barrow Group deltaic sediments of the Exmouth Plateau were mapped with forty seismic lines and data from five wells. The mapping shows two deltaic sequences which are separated by a flooding surface. The source areas ... -
Muscovite 40Ar/39Ar Geochronology of the Western Parry Sound and Britt Domains, Central Gneiss Belt, Grenville Province
(1991-04-15)40Ar/39Ar analysis of ten muscovite samples from the western Central Gneiss Belt, Grenville Province, Ontario, yielded good argon spectra. The ages calculated show a trend of decreasing age southward into the orogenic ... -
Correlation and 40Ar/39Ar Age Dating of the Early Cretaceous Walker Island Member Basalts Axel Heiberg Island - Canadian Arctic
(1991-04-15)Previous studies have documented the presence of magnetic polarity reversals, which could represent the earliest M0 or M1 reversal of the M-Sequence, in the Early Cretaceous (Aptian-Barremian) sedimentary/volcanic stratigraphic ... -
The Petrochemistry and Origin of the Bourne Complex, Northwestern Ellesmere Island, Canada
(1991-04-15)New petrological and petrochemical analyses provide insight into the origin of the hypabyssal and volcanic rocks of the Bourne Complex, northwestern Ellesmere Island, Canada. Field relationships and petrographic characteristics ... -
Origin of Foliation in the Barrington Passage Pluton
(1991-04-15)New studies provide insight into the processes producing the penetrative foliation observed in the Barrington Passage Pluton (BPP). Preferred alignment of primary minerals, imbrication of feldspars, preferred alignment of ... -
Thermobarometry of Meta-Sedimentary Enclaves in the Ten Mile Lake Intrusion, Liscomb, Nova Scotia
(1990-04-15)A section of a drill core from the area of the Ten Mile Lake, Liscomb Complex, Nova Scotia, contains many small metasedimentary enclaves in a felsic host. The enclaves investigated are calc-silicate and metapelites and ... -
Geophysical Modelling of the LaHave Clay and Emerald Silt Formations, Lahave Basin
(1990-04-15)A seismic reflection profile across part of the LaHave Basin shows 4 continuous, strong reflectors. This study relates the observed seismic reflection data to the measured physical properties (velocity, density, porosity, ... -
Magnetic Anomalies Near Ore Bodies and Mineralized Zones in the Troodos Ophiolite of Cyprus
(1989-04-15)The Troodos ophiolite in southwestern Cyprus has been a major producer of copper since the Bronze age. As such, the area has been studied and mapped extensively, and most known mineralized areas have been studied. Preliminary ... -
A Geochemical Study of the Carboniferous Audhild Volcanics, Northwestern Ellesmere Island, Arctic Canada: Initial Volcanism in the Sverdrup Basin
